The second-order rate constant for the dimerization of a protein (P) P + P → P2 is 6.2 × 10−3/M · s at 25°C. Part 1 out of 2 If
siniylev [52]

Answer:

r=1.59\times 10^{-10}\ M/s

Explanation:

According to the law of mass action:-

The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.

Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.

The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.

From the reaction given that:-

P+P\rightarrown P_2

The expression for the rate is:-

r=k[P]^2

Given that;- k= 6.2\times 10^{-3} /Ms

[P] = 1.6\times 10^{-4} M

Thus,

r=6.2\times \:10^{-3}\times \:\left(1.6\times \:\:10^{-4}\right)^2\ M/s=1.59\times 10^{-10}\ M/s

In this equation, stands for carbon, stands for nitrogen, and stands for oxygen. Which equation represents this reaction?
Marat540 [252]
In order to answer this question we must look at the image which I have attached.

The red atoms refer to oxygen atoms, the grey atoms are carbon atoms and the blue atoms are nitrogen. Therefore, the equation from the image suggests:

2CO + 2NO → 2CO₂ + N₂

Looking closely at the options given, several of them could be eliminated immediately since they are not balanced equations like B, C and E. Therefore, only A or D could be the answers.

The answer is option <span>D.) 2CO + 2NO → 2CO2 + N2

Which of the substances has polar interactions (dipole–dipole forces) between molecules?
Yuki888 [10]

<u>Answer:</u>

CHCl3 has dipole-dipole interactions.

<u>Explanation:</u>

Trichloromethane has a electric dipole moment permanently pointing along the line parallel with the Hydrogen carbon axis.Dipole-dipole interactions are said to be intermolecular force of  attractions that is formed from two permanent dipoles interacting.

These type of interactions  are occurring when one of the partially charged formed molecule are  being attracted to an opposite partially charged molecule  nearby . The molecules align in a state that the positive end of one of the molecule  gets interacting with the negative end of the another molecule.

How do I find the rate of reaction on a graph
Nonamiya [84]

Rate of reaction can be understood as the rate of change of the materials, such as the rate of depletion of the reactants or the rate of production of products.  Therefore, if a graph of concentration and time is plotted, the rate of reaction is simply the slope of the graph.
